Abstract

The invention discloses a method for manufacturing a braze-welding had material millstone from a waste blade. The method comprises the following steps of: (1) crushing the waste blade into particles with a particle diameter ranging from 2.0mm to 6.0 mm; (2) uniformly coating paste welding flux on a metal matrix; (3) uniformly spreading hard particle particles onto the metal matrix coated with the paste welding flux, and pressing the hard material particles into the paste welding flux; and (4) putting workpieces obtained in step (3) into a vacuum oven, and taking out the workpieces to cool, thereby obtaining the braze-welding had material millstone, wherein a welding temperature ranges from 800 DEG C to 950 DEG C. Compared with the prior art, the method has the advantages that: the waste blade is manufactured into the hard material millstone, and is used for processing steel, stones and the like, so that waste can be utilized, and processing efficiency further can be improved.

Description

technical field [0001] The invention belongs to the technical field of superhard materials, and in particular relates to a method for preparing brazing hard material grinding discs by using waste blades. Background technique [0002] At present, a large number of hard material cutting tools are used in the manufacturing industry, such as cemented carbide, cermet, diamond blades, ceramic blades and PCBN blades. A lot of waste of resources, especially cemented carbide, which contains a lot of non-renewable resources cobalt and tungsten. Although there are currently recycling methods for hard composites, the recycling process is more polluting. Ceramic blades, cermet blades, diamond blades and PCBN blades are currently discarded directly after use. Contents of the invention [0003] The object of the present invention is to provide a method for preparing brazing hard material grinding discs by using waste blades to address the shortcomings of the prior art. [0004] The pur...
